This page provides a backpacking gear list for day hikes, overnight backpacking, and long-duration trekking -- in Spring, Summer, Fall, and Winter.
The focus is on backpacking gear required for safe travel in moderate mountain environments (e.g., Cascades, Olympics, Sierras, Rockies, etc.).
The backpacking gear list is offered as a baseline for you to work with and will need some adjustment to meet your specific needs, for your part of the world and/or for those places to which you travel that have unique requirements.
Ultimately, each one of us must be responsible for determining our own gear needs in the backcountry.
